What is comtradr?

comtradr's 1.0 line is a long tail of patches against a brittle UN trade API.

comtradr wraps the UN Comtrade API for international trade data in R, handling authentication, reference tables, caching and bulk downloads. The entire visible window is the 1.0 patch series: six releases, most of them repairs. The substantive additions are a variable-metadata reference table and automatic request splitting.

What is tulpa?

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

2.5

comtradr's 1.0 line is a long tail of patches against a brittle UN trade API.

◆ Current state

comtradr wraps the UN Comtrade API for international trade data in R, handling authentication, reference tables, caching and bulk downloads. The entire visible window is the 1.0 patch series: six releases, most of them repairs. The substantive additions are a variable-metadata reference table and automatic request splitting.

◆ Where it's heading

The work is defensive, shaped by the API's constraints rather than by a roadmap. The 1.0.6 fix is representative: Comtrade rejects URLs longer than about 2000 characters, so the package now detects that before the request and transparently splits and recombines it. Running alongside is steady dependency hygiene, most recently swapping poorman for dplyr ahead of a CRAN archival.

◆ Prediction

The release pattern points to more of the same, with error-message and edge-case repairs as users hit new API limits, rather than new endpoints.

The 0.0.x train stops at CRAN: tulpa's engine ships to the ecosystem it already anchors.

◆ Current state

tulpa is the C++/R Bayesian spatial inference engine sitting under gcol33's family of ecological occupancy packages, tagging 0.0.x releases several times a week. 0.1.0 is its first CRAN release, and the notes state outright that the engine surface is unchanged from 0.0.198 — the work is packaging discipline: local T bindings rebound to n_t/n_times, OpenMP teams capped under R CMD check, the pkgdown deploy narrowed, an aspell dictionary added. The window behind it splits between the S3 generics conversion and numerical-correctness work in the nested-Laplace grid.

◆ Where it's heading

Two moves in nine days point at the same destination: the generics conversion made tulpa extensible by downstream packages, and CRAN admission makes it installable by them. The current cadence — several tags a week, some existing only to record a measurement that produced no code change — does not survive CRAN's submission overhead, so the release rhythm has to slow whether or not the project intends it. The correctness work still clusters on the joint nested-Laplace driver, and 0.1.0 extends the same diagnostics habit with .NL_AXIS_SD_REASONS, a closed vocabulary for an outer axis whose grid does not contain its own posterior mode.

◆ Prediction

Expect tulpaObs to follow tulpa onto CRAN, since it is the consumer whose registrations the engine has spent this window unblocking, and expect the version line to move in larger, less frequent steps now that each one carries a submission.
